Since we don't have a PC yet, we now have gotten to the point of spawning BRF PF cakes to hpoo/coir bulk casings made from pint jars.
Too many variables go into determining if length of colonization in our case is dependent upon jar size, because we were working with two different strains (both multispore), and the one had additives, and never tried halfs.
The good part about whole pints is that there is less labor involved with needle flame sterilization between inoculation points, less jar washing/filling, less lids to make up, with half the risk of contamination.
But the bad part is that when one goes, it's really like losing the material of two.
The pint jars are more convenient for everyday household use when they aren't being used for science experiments.
We look forward to going to grain/WBS isolate soon. That will be the ultimate.
